BIOTRONIK has released its Idova 7 series of ICDs (implantable cardioverter-defibrillators) and CRT-Ds (cardiac resynchronization therapy defibrillators), the only devices with a 45 joule energy delivery that are also MR compatible. The defibrillators are able to recharge their capacitors within ten seconds to get ready for additional shocks, and the battery is promised to last for up to 11 years of operation.

Cardiologists tend to identify a patient’s defibrillation threshold (DFT), the amount of energy needed to cardiovert the heart back into a sinus rhythm, before placing the implant. The concern is that this threshold may rise over time, while the implant’s maximum energy delivery ends up below it. BIOTRONIK believes the new implant will offer more peace of mind to patients and their physicians that the shock delivered will be sufficient, even on the first attempt.
